This invention relates to fluid coating machines of the kind used in themanufacture of footwear, and more particularly to a cementing machinefor applying cement to welt lasted uppers prior 5 to afiixing an outsolethereto.

A general object of the invention is to provide a bottom cementingmachine which is adapted to handle welted uppers so as to apply acoating of cement to the welt and inseam portions m thereof.

More specifically, objects of the invention are to provide a cementapplicator having a work support which is adapted to hold the extendededge of 'a welt against the applicator surface to insure proper fluidapplying contact between it and the welt.

A further object of the invention is to provide a welt supportingattachment which may be used with existent forms of bottom cementingmachines.

, Other objects of the invention will in part be obvious and will inpart appear hereinafter.

The invention accordingly comprises the features of construction,combination of elements,

and arrangement of parts, which will be exemplified in the constructionhereinafter set forth and the scope of the invention will be indicatedin the claims.

For a fuller understanding of the nature and objects of the inventionreference should be had to the following detailed description taken inconnection with the accompanying drawing, in which:

Fig- 1 is a fragmentary top plan view of a bottom cementing machineequipped with a welt support constructed in accordance with theprinciples of the present invention; and

Fig. 2 is a vertical sectional view taken alon line 2-2 of Fig. l.

It is now becoming the practice to the outsoles of welt type shoes towelted uppers by means of cement instead of by stitching. In followingthis recently developed practice, the upper is lasted in the usual orany suitable manner, for example by the familiar steps used inconstructing a Goodyear welted shoe, and the inseam thereof is closelytrimmed. The inseam and welt are roughed to provide a suitable sur-'face for cementing. The cement is applied to such roughed inseam and tothe bottom of the welt and preferably also marginally around an outsole.These parts are then stuck together in a sole press. The cement may beapplied by any suitable type of bottom cementing machine now in use forhandling non-welted uppers of McKay or related types, provided it has anapplicator capable of covering the welt and inseam area.

When cementing welts, care must be taken to see that the extended weltedge, which is un- 5 supported by the last, is held in cement receivingrelationship against the face of the applicator. The present inventionprovides a device especially suited for doing this which is capable ofbeing mounted on any suitable type of bottom cementing machine, beingherein illustratively shown mounted on a cementer of the kind shown inthe copending application of William C. Card, Ser. No. 105,180, filedJanuary 4, 1934.

Referring more particularly to the drawing, 15 there is shown the upperportion of a cement applying machine having an applicator it with a rimll of rubber or like compressible material which is adapted to havecement deposited on its periphery by means of a cement transfer 20 wheelit which in turn has cement deposited thereon by any suitable means, forexample that shown in the above mentioned Card application.

A drive shaft I3, which is adapted to be driven in any suitable manner,is provided for the ap- 5 plicator l0, and the shaft and applicator inare preferably mounted in inclined position, as shown in Fig. 2, so thatthe lower work engaging periphery of the latter is positioned so as toenable the operator to see the work at the point of 30 cementapplication. A hinged cover it is provided, which has a forwardlyextending portion l5 closely overlying and covering the upper end of theapplicator Ill. a

A threaded pintle I6 is provided in such cap 35 portion and is adaptedto provide a hearing about which the applicator may be rotated, and alsoto hold' such applicator in position with respect to its drive shaft,there being a slot and, tenon connection ll between these parts which 40permits removal of the applicator when desired. These above disclosedparts are constructed in accordance with the showing in the mentionedCard application.

In order to handle welted work in an improved 45 manner, a block I8 isscrewed to the cover extension it: by means of screws is which areextended through slots 20 to enable the block to be adjustablypositioned on the cover. Such block is recessed as at 21 to accommodatethe 50 pintle l6 and it has a. pair of hollow bores 22 extendinglongitudinally thereof. A removable welt support holder 23 is providedwith pins 24 which extend slidably into bores 22 to permit guidedmovement of such holder with respect 55 means of a screw 2? passingthrough a slot 2% which permits vertical adjustment or" the support inrespect of its holder. The downwardly extending portion of this supportterminates in a tapered finger 29 which is adapted to enter the weltcrease of a lastedwelted upperso that its'facc 3t serves to hold theextended edge of the welt in cement receiving contact with the applyingperiphery of the applicator, spring 25 acting to give the welt a slightspring tension against the applicator 'face and also yielding toaccommodate diiierent thicknesses of work. A guide shoul der 3i isprovided on the welt support in position to engage the edge of the weltand prevent it from moving upwardly, beyond the cement bearing surfaceof the applicator.

In operation the welt support and holder are pulled outwardly ,by handand the welt and inseam portions of the lasted upper are placed againstthe applicator periphery with the,fin ger of'the welt support located inthe welt crease, after which the support is released in order to enablethe spring 25 to hold the welt against the applicator. The shoe is heldin this position by the operator during ensuing feeding and applyingmovements, until a band of cement is deposited on the welt and inseamportions of the shoe from the heel breast line at one side entirelyaround its forepart and back to the heel breast line at the other side.

Since certain changes may be made in the above construction anddifierent embodiments of the invention could be made without departingfrom the scope thereof, it is intended that all matter contained in theabove description or shown in the accompanying drawing shall beinterpreted as illustrative and not in a limiting sense.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

l. A bottom cementer for welted shoe uppers comprising a. rotatableyieldable applicator roll havinga portion of its periphery exposed forcontacting work presented thereto, means for delivering cement to saidapplicator, and a welt support engageable in the welt crease of a weltedupper comprising a finger having its welt engaging face substantiallyparallel with and located opposite to said workcontacting portion, saidsupport being slidably and yieldably mounted in operating position forstraight-line movement toward and away from said applicator.

2. A bottom cementer for welted shoe uppers comprising a casing, arotatable applicator having a peripheral portion extending from saidcasing for contacting work presented thereto, means for deliveringcement to the periphery of said applicator, a welt support engageable inthe welt crease of a welted upper and slidably mounted on said casing,and spring means giving said support a bias toward said applicator.
